Can you make like a Mario RPG fan game with this?

This engine and all its branches are 2D platformer engines. Using their default functionality won't allow you everything, so, result will depend on your ideas and knowledge of functionality of these engines. You may create a kind of RPG-like game if you use scripts at SMBX-38A or SMBX2 and save various custom data, etc. You may want ask HengShao guy who makes a lot of "black magic" with the SMBX-38A branch. He appears at various SMBX-related Discord servers and on the smbx-world Chinese forum for the SMBX.
But, if you want a game with isometric look and FF-like battles, you may want use different engines than this, or do a serious "black magic" with graphics and mechanics on the SMBX and its branches.

SMBX-38A known as "1.4" is not a "version", it's a completely different game implementation that lives with its own life. "2.0" is also not a version, it's the huge hacking mod over the original SMBX 1.3 binary. Anyway, since February 2, 2020, the source code of the game was been published (you can see the discussion here https://www.supermariobrosx.org/forums/viewtopic.php?f=69&t=25160 ), and some months later, the cross-platform port of the game called "TheXTech" was out (details here https://wohlsoft.ru/f/t3677 ).
